“…The quality of effluent from dairy plants mainly depends on processing parameters (e.g., design, production and operational methods, type of product, etc.) and water management programs 45 . Based on this, the wastewater from dairy plants is based on three major categories 46 : (1) Water utilized in the cooling/heating heat exchangers (due to less pollution, it can be reutilized and/or discharged into the environment without serious concern), (2) Wastewater related to sanitary purposes, and (3) Wastewater related to the process of cleaning different dairy components.…”

Due to the high volume of wastewater produced from dairy factories, it is necessary to integrate a water recovery process with the treatment plant. Today, bipolar membrane electrodialysis units (BMEUs) are increasingly developed for wastewater treatment and reutilizing. This article aims to develop and evaluate (technical and cost analyses) a combined BMEU/batch reverse osmosis unit (BROU) process for the recovery of chemicals and water from the dairy wastewater plant. The combined BROU/BMEU process is able to simultaneously produce water and strong base-acid, and reduce power consumption due to the injection of concentrated feed flow into the BMEU. A comprehensive comparative analysis on the performances of two combined and stand-alone BMEU configurations are developed. The proposed combined technology for dairy factory wastewater treatment is designed on a new structure and configuration that can address superior cost analysis compared to similar technologies. Further, the optimal values of permeate flux and current density as two vital and influencing parameters on the performance of the studied dairy wastewater treatment process were calculated and discussed. From the outcomes, the total cost of production in the combined configuration has been reduced by approximately 26% compared to the stand-alone configuration. Increasing the feed concentration rate using the batch reverse osmosis process for the dairy wastewater treatment process can be an ideal solution from an economic point of view. Moreover, point (current density, feed concentration rate, total unit cost) = $$\left(328.9, 7, 14.37\right)$$ 328.9 , 7 , 14.37 can be considered as an optimal point for the economic performance of the studied wastewater treatment process.
